Magnetic Particle Testing

We have the capabilities to provide Wet Fluorescent and Dry Magnetic Particle Inspection with Yokes, Probes, and Coil. We also have a P-510 Mobile Power Pack with 4000 AMP AC/HWDC capabilities. This unit is perfect for turbine parts such as diaphragms, rotors, and large quantities of stud and bolts. Large enough for bigger projects and mobile enough for field applications.

How It Works

Magnetic Particle Inspection uses electrically induced magnetic fields in parts made from ferromagnetic materials to detect flux leakage at the site.

A magnetic field is induced in the test specimen, which is then “dusted” with iron particles, either dry or in a liquid suspension. The particles will collect along the edges of any cracks or other discontinuities that distort the induced magnetic field to provide a readily visible indication of the flaw.

While limited to examining parts made from iron and steel which are strongly affected by magnets (ferromagnetic), Magnetic Particle Inspection is very useful for detecting minute surface and near-surface cracks down to a depth of about 0.100”. Magnetic Particle Inspection is used to test a wide variety of raw or manufactured materials and components, including castings, forgings and weldments, safety critical automotive parts, and infrastructure, such as bridges or storage tanks.
